LATHE ATTACHMENT FOR TURNING BEARINGS.

To all whom it may concern:

Be it known that I, CARL PHILIPP, citizen of the United States, residingat Jackson, in the county of Jackson and State of Michigan, haveinvented certain new and useful Improvements in Lathe Attachments forTurnmg Bearings, of which the following is a specification.

My invention relates to an improvement in lathe attachments for turningbearings, and the object is to provide means for turning off tumblingshaft bearings and cranks without cutting off the ridge rod arm of thetumbling or reverse shaft of locomotives.

A further object is that the attachment can be applied to any lathe, or,if desired, can be used independently of a lathe.

The invention consists of certain novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claims.

In the accompanying drawings :Figure 1 is a view of the inventionapplied to a lathe; Fig. 2 is a view in side elevation of the attachmentFig. 3 is a sectional view through the pinions and gears and 4 is adetail.

A represents the bed of the lathe, and B is a tool post mounted thereon.

C is a bearing or head which is provided with a curved aw 1, the jawhaving flanges 2 thereon. The shank 3 of the bearing received in thetool post B for supporting it in its operative position.

Gears 4, 4 are connected together by webbing 5, and are made in twosections, the gears having recesses 6, 6 formed in the webbing which arecounterborcd to receive the flanges 2 of the bearing 0. The gears areconnected together by the ordinary tap connection. The jaw 7 isconnected to the jaw 1 by screw bolts 9 passing through the flanges 10and 11 on the jaws 7 and 1, respectively, thereby holding the sectionalgears upon the head C. The outer surface of the jaw 7 e tends outwardbeyond the gears 4, preventing anything from coming in contact with thegear teeth at the forward end of the at I tachinent.

A curved arm 12- is connected to the shank 3 of the bearing C, which isprovided. with a forked end 13. Pinions 14, 14, are made integral withtheir sleeve and are mounted upon a shaft 15 in the forked end of thearm 12, the shaft 15 passing through the forked end of the arm. Pinions14 are adapted to engage the gears 4, and the pinions being ro-Specifieation of Letters Patent.

tated through the shaft 15 thereby cause the gears 4 to rotate.

Located in suitable guide recesses in the sides of the gears are cuttersor knives 17, they being adj ustably held in the recesses by screws 19,which extend through elongated slots 20 in the knives.

The shaft or piece of machinery to be operated upon'is passed throughthe central opening of the gears 4 and supported upon the lathe in theusual manner between cen ters. After this has been accomplished, poweris transmitted to the shaft 15, which causes the pinions 14 to rotateand through their engagement with the gears 4 the gears are rotated andthe shaft operated upon by the cutters or knives.

The attachment is capable of alongitudinal as well as horizontaladjustment, the shank 3 of the bearing being adjustable in the post B,and the post which is mounted u on the bed of the lathe, is capable of alongitudinal movement.

From the foregoing it will be seen that I have provided a very simpleattachment which can be applied to any lathe for truing bearings ofshafts, which attachment may be used independently of a lathe ifdesired. By this attachment the shafts can be properly centered and thebearings operated upon in any approved manner for truing them.

It is evident that more or less slight changes might be resorted to inthe form and arrangement of the several parts described withoutdeparting from the spirit and scope of my invention, and hence I do notwish to be limited to the exact construction herein set forth, butz-Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a lathe attachment for turningbearings, the combination with a head, of gear wheels having recessestherein for supporting the gears upon the head, means c0nnee-ting thegears together for retaining them in position on the head, cutters onthe gears, and means for rotating the gears.

2. In a lathe attachment for turning bearings, the combination. with ahead having flanges thereon, of gears made in sections, said gearshaving recesses therein in which the flanges of the head are receivedfor sup porting the gears on the head, a Web connecting each section ofthe gears together for retaining them in position, a driving shafthaving pinions thereon in engagement with on the flange of thefirst-named aw, a driv- 10 the gears for rotating the gears, and cuttersing shaft having pinions in engagement with on the gears. the gears, andcutters on the gears.
